heroinThe director of Russia’s Federal Narcotics Control Service said on Tuesday that Turkish laboratories are processing Afghan opium into heroin for deliveries to Europe.

According to Russia’s Sputnik news, Viktor Ivanov said that Russian and Afghan drug police confiscated more than 600 kilograms (over 1,300 pounds) of opium in a joint operation in December.

“The cargo traveled along the route of Badakhshan-Doshi-Bamiyan-Herat, then further through Iran and into Turkey, where the opium was processed in well-equipped laboratories … into high quality heroin, and then was to be sent to Europe and Russia,” according to Sputnik, Ivanov said during an anti-narcotics committee meeting.

Last week, Ivanov said that large shipments of Afghan heroin were being transited through Turkey into the Balkan states and on into the European Union.

Ivanov says the drugs from Afghanistan generate profits estimated at $150 billion annually for the people involved in the operations with them.

His comments come as Afghanistan has been designated among 22 countries as “major drug transit and/or major illicit drug producing countries” for 2016.

President Barack Obama said in September that “Illegal poppy cultivation in Afghanistan is among the most difficult international drug-control problems.”
